For backward compatibility, the DataServer supports the RECID function for Oracle tables that have a PROGRESS_RECID column. The OpenEdge DB-to-Oracle conversion utility creates an indexed NUMBER column, called PROGRESS_RECID, with unique values for each row. You can also add this column to Oracle tables manually. See Manually adding PROGRESS_RECID to Oracle for instructions.

You can make an existing application that includes RECID behave more consistently across data sources by replacing RECID with ROWID. See the for more information.
